New fears on sea-level rise
new cubs. Previous research has already shown that unstable ice can result in failures of on-ice denning attempts. Less ice than is suitable for denning apparently has led to an increased frequency of pregnant polar bears in this region choosing to den on land, " says Fischbach. Unlike other temperate and Arctic bear species that hibernate during winter months, polar bears remain active and sea...
متن کاملContemporary sea level rise.
Measuring sea level change and understanding its causes has considerably improved in the recent years, essentially because new in situ and remote sensing observations have become available. Here we report on most recent results on contemporary sea level rise. We first present sea level observations from tide gauges over the twentieth century and from satellite altimetry since the early 1990s. W...
متن کاملNew Perspective on Global Warming & Sea Level Rise: Modest Future Rise with Reduced Threat
Sea Level Rise (SLR) in response to the present and future warming of the earth’s surface is probably the most contentious issue being debated at present. This brief commentary surveys the most recent literature on ongoing SLR and on the major factors contributing to future rise. It is concluded that the best guess value of SLR for the next 100 years is a relatively modest 23 cm +/− 5 cm which ...

متن کاملSea-level Rise Forecast Model
The paper analyzes the melting pace of ice cap in the North Pole and its influence on the rising sea level. The paper constructs the linear and non-linear models between rising sea level and the year by quoting data from Florida Tide Gage Station. The paper also contrasts the two models and selects the non-linear model. By adopting the model, the paper predicts the height of rising sea level ev...
